I'm having this problem even with python_egg_path defined as: "SetEnv PYTHON_EGG_CACHE /tmp/". The same directive was used in older versions of trac sucessfully. Either this is a problem with trac or with genshi 0.5 (i've not managed to exclude that option yet)
This directive is ignored…
I'm changing the severity to major as Genshi defaults its install method to zipped egg…

I've the same problem while upgrading from Trac 0.11dev-r6658 to HEAD. The Apache directive is ignored.
comment:4 by , 17 years ago
Also having the same issue. Setting ENV PYTHON_EGG_CACHE did not work for me neither. Reinstalled Genshi 0.5 / Trac 0.11rc2 did not make a difference.

Found the answer on the net, some other guy having the same issue. Solution: Extract Genshi egg as a directory under the same egg name.

Trac 0.12dev-r7204 on Fedora 8, apache (httpd-2.2.8-1.fc8) still gives:
[Thu Jun 12 18:10:57 2008] [error] [client 192.168.1.90] ExtractionError: Can't extract file(s) to egg cache\n\nThe following error occurred while trying to extract file(s) to the Python egg\ncache:\n\n [Errno 13] Permission denied: '/root/.python-eggs'\n\nThe Python egg cache directory is currently set to:\n\n /root/.python-eggs\n\nPerhaps your account does not have write access to this directory? You can\nchange the cache directory by setting the PYTHON_EGG_CACHE environment\nvariable to point to an accessible directory.\n
Adding:
SetEnv PYTHON_EGG_CACHE /tmp
inside the
<Location /trac>
block didn't help.
The quick/simple fix is to add to the end of: /etc/sysconfig/httpd export PYTHON_EGG_CACHE=/tmp
Then restart Apache.

FYI: this worked for me too. Thank you very much davidck.

Hey
For anyone still clueless I did the following.
added the environment variables (Im not sure if this has any affect) by changing
/etc/apache2/sites-enabled/trac to:
<Location /trac>
SetHandler mod_python PythonInterpreter main_interpreter PythonHandler trac.web.modpython_frontend PythonOption TracEnvParentDir /var/lib/trac PythonOption TracUriRoot /trac SetEnv PYTHON_EGG_CACHE /tmp
</Location>
Then: easy_install -m genshi went to the python directory /usr/lib/python2.5/site-packages$ deleted the genshi egg ran easy_install -z genshi==0.5
comment:9 by , 16 years ago
I can not understand what just happened. I updated from 0.11b1 to 0.11, and all of a sudden when I restarted apache2 my SetEnv PYTHON_EGG_CACHE was no longer taken into respect.
AFAICR I didn't modify Apache in since I last restarted it… :-/
Is this a Trac 0.11 issue or an Apache 2.2 mod_env bug/vagueness?

Should be
easy_install -Z genshi==0.5
-Z option ensures the egg is unzipped when installed

This worked for me, too, and was the only method that worked (tried the other methods as well)

Set PYTHON_EGG_CACHE using PythonOption
comment:15 by , 16 years ago
The main issue here is that we can't set the env variable PYTHON_EGG_CACHE
from values passed using SetEnv
since these values are only available at request handling time and not at the initial import.
attachment:modpython_egg_cache.patch uses a different approach and instead uses a global PythonOption
:
PythonOption PYTHON_EGG_CACHE /some/path
But for this to work this statement needs to be placed outside any virtualhost or location section.

I can not set the PYTHON_EGG_CACHE, using
apache-2.2.9 trac-0.11_2
Have tried inside
<Location> Set PYTHON_EGG_CACHE /some/path …
and aslo directly into httpd.conf with; PythonOption PYTHON_EGG_CACHE /some/path
Is there really no way of changing the PYTHON_EGG_CACHE?
comment:18 by , 16 years ago
I've been able to solve this on BSD (apache 2.2.9 + mod_python) creating a trac.env
file under /usr/local/etc/apache22/envvars.d
which reads
export PYTHON_EGG_CACHE=/tmp
This has the effect of exporting the PYTHON_EGG_CACHE variable to the apache process on startup. Any similar trick in your favorite Un*x/Apache flavour should work.

suCrabu, that's a beautiful fix for us BSD users, thanks! I'll use this until FreeBSD ports gets sync'd up with the next release.
comment:20 by , 16 years ago
tried suCrabu's "fix", with no luck. http-error.log still reports the value to be ""
Grrr, I hate it when things like this break for no good reason.
This is an installation issue (and as such should have been posted to the MailingList).
The root cause of the error is shown in the last line:
and the solution to resolve it is also printed out…
